无法在C ++中嵌入XCode 4项目中安装libjson [英] Cannot Install libjson in c++ Embedding in XCode 4 Project

问题描述

我根本不知道如何将libjson安装为我的c ++项目的一部分。我已经通过一切在线。嵌入在我的项目。

I simply cannot figure out how to get libjson installed as part of my c++ project. I've been through everything online. Am embedding this in my project.

首先我尝试了

1. 将libjson目录移动到我的项目
2. 
   
3. 已注释掉：#define JSON_LIBRARY


4. 换行


5. 添加#includelibjson / libjson.h

Project builds ok ..

Project builds ok..

file：

JSONNode n = libjson::parse(json);

构建失败，出现两个错误：

Build fails with two errors:

Undefined symbols for architecture x86_64:
  "JSONWorker::parse(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)", referenced from:
      libjson::parse(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)in main.o
  "internalJSONNode::deleteInternal(internalJSONNode*)", referenced from:
      JSONNode::decRef()     in main.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

我也试过make& sudo make手动安装和编译项目。相同的错误：

I've also tried make && sudo make install and compiling the project manually. Same errors:

g++ main.cpp -o junk -I/usr/include/libjson -ljson

我也尝试过：

SHARED=1 make && sudo SHARED=1 prefix=/usr/local make install

最后，我试过复制libjson文件到我的项目，也得到相同的错误。

Finally, I've tried copying the libjson file into my project and also get the same errors.

有人可以告诉我我做错了什么？我们使用rapidjson，但更喜欢libjson的外观。主要问题是我们无法安装它！

Please can someone show me what I'm doing wrong? We were using rapidjson but prefer the look of libjson. The major problem is that we cannot install it!

推荐答案

我回答自己的问题，因为这是一个痛苦颈部。

I'm answering my own question because this was a pain in the neck. Here's what I did to get it working.

1. 在JSONOptions.h中注释#define JSON_LIBRARY


2. 运行make


3. 将libjson.a添加到您的项目


4. 将JSONOptions.h添加到您的项目


5. 将#includelibjson.h添加到您的主项目文件中

1. Comment out #define JSON_LIBRARY in JSONOptions.h
2. Run make
3. Add libjson.a to your project
4. Add libjson.h to your project
5. Add JSONOptions.h to your project
6. Add #include "libjson.h" to your main project file

$ b b 。希望你不浪费我这么多的时间...

Voila. Hope you don't waste as much time as I did on this...
